Title: Improvements in or relating to power-assisted steering systems particularly for motor vehicles
IPC: B62D5/30
Filed: 1962-01-22
Abstract: 926,831. Vehicle power steering. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Jan 22, 1962 [Feb. 18, 1961], No. 2183/62. Class 79(5). A power-assisted vehicle steering system comprises two continuously driven pressure medium pumps 3, 12 and a change-over valve 15 which operates automatically upon interruption of the supply of pressure medium from the pump 3 to a servomotor 2 to connect the servomotor to the pump 12. The pump 3 is driven by the vehicle engine and the pump 12 is driven through a one-way clutch from the gearbox output shaft or from the back axle. Alternatively both pumps may be driven by the vehicle engine. The changeover valve 15 (Figs. 3, 4) comprises an axially displaceable control piston 20 having annular grooves 26, 27, 28 co-operating with annular grooves 24, 25 in the bore 19 of a housing 18. The pressure of fluid supplied from a reservoir 8 by a pump 3 through a delivery pipe 4a to a chamber 23 normally overcomes the force of a spring 21 to retain the piston 20 in the position shown wherein the fluid supplied by the pump 3 passes via radial channels 32, the annular grooves 28, 25 and a pipe 4a to the servomotor 2 whilst fluid supplied by the pump 12 through a pipe 4b passes via the annular grooves 27, 24 and a return pipe 17 to a pipe 6 which returns fluid from the servomotor 2 to the reservoir 8. When the supply of fluid from the pump 3 to the chamber 23 is interrupted the spring 21 displaces the piston 20 whereby the grooves 27, 25 communicate to connect the pipe 4b to the pipe 4 and the control edges 37 of the grooves 28, 25 engage to disconnect the pipe 4a from the pipe 4. During piston displacement back pressure is prevented by connecting a chamber containing the spring 21 and the groove 24 with a passage 34 and by arranging that the chamber 23 is connected via a bore 30 and the grooves 26, 27 with the return pipe 17 before the control edges 37 engage. In Fig. 2 (not shown) the servomotor is supplied through two interconnected change-over valves from any one of two pumps driven by separate engines and one transmission driven pump. The two changeover valves may be combined in a single unit and the pumps may have individual pressure medium circuits with separate reservoirs and return pipes controlled by the change-over valves.

Title: Improvements in loom let-off motions
IPC: D03D49/06
Filed: 1927-01-25
Abstract: 265,194. Maschinenfabrik R³ti vorm. C. Honegger. Jan. 30, 1926, [Convention date]. Letting-off warps.-In let-off motions of the kind in which the tension of the warp is maintained constant by means of a warp-beam feeler, the beam is allowed to rotate by a ratchet-driven worm meshing with a worm wheel on the beam, the operation of the ratchet-driving devices being controlled by the warp-beam feeler and by devices dependent upon axial motion of the worm which is normally held in a central position by the action of a weight or spring, but which is displaced when abnormal tension occurs. The warp-beam 1, Fig. 1, is provided with a wormwheel 3 meshing with a worm 6 splined on a shaft provided with a ratchet wheel 31 and a hand wheel 19. The worm is connected to a lever 7 pivoted to a lever 9 on a shaft 10 controlled, i an adjustable spring 12, the arrangement normally holding the worm 6 in a central position. The effective leverage of the levers 7. 9 is adjusted from time to time by a screw-operated pivot 8 between the levers, the end of an indicator arm 14 controlled by the feeler being maintained over the pivot 8, as shown. The ratchet wheel 31 is operated by a ratchet 30 on a lever 26 adjustably connected to a lever 20 which is rocked by a rod 27, Fig. 3, adjustably pivoted to a slotted arm 24 oscillated through bevel gearing by a. slotted lever 21 connected to a reciprocating rod 20. As the diameter of the warp on the beam decreases, a rod 17<1> connected with the feeler 17 rises and raises the rod 20 in the slot in the lever 21, whereby greater motion is transmitted to the ratchet wheel. When the tension varies, the worm 6 is displaced against the action of the spring 12 from its normal position and thereby turns the shaft 10, and an arm on the shaft 10 effects displacement of the rod 27 in the slotted arm 24 to vary the rate of let-off until the tension has again become normal. The levers 25. 26 are slotted to receive an adjustable pivot bolt 28, the lever 25 being provided with graduations 29 corresponding to different weft thicknesses.

Surface undulations on a moving web of material (e.g. creases in paper) are sensed by a straight rounded edge of a resilient feeler plate member 1 (Fig. 1) to which is fixed a resistance strain gauge 2. There may be two strain gauges on the plate 1 and connected in a bridge circuit to produce a voltage indicative of a fault or surface irregularity, and the voltage may be used to actuate a web marking device (not shown), or the duration of the signal may be used to indicate the length of a fold for instance. To prevent oscillation of the feeler plate there is provided a leaf spring damper member 3 acting against the plate through a foam rubber block (6) Fig. 1a (not shown), and adjustably biasing the feeler edge against the material surface. The feeler edge may be a fixed cylindrical rod or it may be mounted to the feeler plate for rolling on the web surface. The angle of the plate relative to a holder 10 to which it is pivotally attached, is adjustable by means of a cam (9) Fig. 1a (not shown). The bridge output may be fed to a recorder. Slow variations of the gauge resistance due to temperature may be avoided by connection to an R. C. coupled amplifier having a suitable time constant.

Abstract: 890,632. Reciprocating pumps. BUDZICH, T. Jan. 23, 1960, No. 2545/60. Class 102(1). [Also in Group XXIX] A hydraulic pump or motor comprising a rotatable cylinder barrel 24, Fig. 1, splined to a drive shaft 32 and formed with a plurality of parallel bores 36 reciprocably mounting pistons 37, includes a cam-plate 43 rotatable about an axis inclined to the axis of the cylinder barrel to adjust the stroke of the pistons. The cam-plate 43 bears against a fixed cam-plate 54 having the same angle of inclination as the cam-plate 43 so that the angular displacement of the combination is half that of the cam-plate 43. In a modification, the fixed cam-plate 54 is replaced by a cam-plate 55, Fig. 4, rotatable about the axis of the cylinder barrel. In this construction, both plates may be rotated together so that on rotation through 180 degrees from the Fig. 4 position, the pistons will remain in their " no-stroke " position. This artifice allows flow through the pump or motor to be reversed. Steep angle cam-plates 551, Fig. 7 and 431, Fig. 9, may replace the cam-plates 55, 43 respectively so that to vary the pump or motor output between maximum and zero requires less angular adjustment of the cam-plate 431.
